Ruanda-Urundi

Ruanda-Urundi was a mandate of Belgium that existed from 1922 to 1962, with Usumbura serving as its capital. The colony was once part of German East Africa, and it was occupied by Belgium during World War I, becoming a League of Nations mandate under Belgian rule in 1922. After World War II, Ruanda-Urundi became a United Nations trust territory, but the mandate split into the countries of Rwanda and Burundi when it gained independence on 1 July 1962.
